Nanostructured hybrids that combine metals and semiconductors exhibit significant potential as photocatalysts for various reactions. Among these, core–shell plasmonic noble metal–semiconductor nanostructures, such Au/ZnO nanostars (NSs), are highly effective catalysts photocatalytic water splitting. This study presents a simple method synthesizing NSs comprehensively characterizes them by using spectroscopic microscopic techniques. The synthesized very high efficiencies in hydrogen (H2) oxygen (O2) evolution when used catalyst heightened activity can be attributed to the efficient suppression of scavenging Au nanoparticles. Additionally, anisotropic star-shaped morphology component contributes an increased surface area promotes enhanced interaction between catalyst's components. facilitates facile interfacial charge transfer at interface, resulting improved performance. Moreover, response core surrounded ZnO nanostructures enhances light utilization capability, contributing its superior synthesis represents advancement paves way future developments design plasmon-semiconductor energy conversion applications.
